I'm trying to model semi elliptical part through circumferential crack on a pipe. I'm getting different values of stress intensity (max. energy release criterion) for different mesh densities/configurations. What could be the possible reason?

I do not have any solution
I do not have any solution for you. I read in different publications that in contrast to the assumption of a completely indepence of the mesh density, there is a explicit dependency on it.
How much do the solutions differ?
